Far northern rivers are discharging increasing amounts of freshwater into the Arctic Ocean, due to intensified precipitation caused by global warming, say researchers at the Hadley Centre for Climate Prediction and Research in the United Kingdom.
Water exchange between the ocean, atmosphere, and land is called the global hydrological cycle. As Earths climate warms, the rate of this exchange is expected to increase. As part of this process, high-latitude precipitation and, consequently, river runoffs are also expected to increase. This could change the distribution of water on Earths surface, with important social and economic consequences.
It could also alter the balance of the climate system itself, such as the Atlantic thermohaline circulation, a kind of conveyor belt. Cold water flows southward in the Atlantic at great depths to the tropics, where it warms, rises, and returns northward near the surface. This flow helps keep northern Europe at a temperate climate, whereas the same latitudes in North America are sparsely settled tundra or taiga.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
